Implement usage of common encoder for both 2D and 3D rendering

Currently we have separate encoders for 2D and 3D rendering and because of this we need to end more encoders when we have both 2D and 3D rendering components. This can be a bottleneck for stress testing scenarios like RenderPerfTest.

We need to verify whether we can use common encoder for both 2D and 3D rendering paths and check if it improves performance numbers in RenderPerfTest.
